Ok, now you are an expert on India as well, don't think you have any idea.
.They are driving Accent, Elantra, Sonata and Terracan as well,just not Santro, except those who are into Terracan type vehicles prefer the rugged Endeavour well proved Pajero over unreliable Terracan, and unreliability of Hyundai vehicles is no fiction, its pure fact, you can see that in US as well, as for Hyundai being a best car company in US, now thats what I call perfect storytelling. As JHZR2 described above, the Suzuki 4WDs are known for their ability to handle rugged territory, this is due to their minimalistic and simplistic design principle, the Vittara was no exception, for the price paid, it does its job and quite well.
About Toyota 4 Runner, the rust issue is due to poor maintenance, I know many rust out their G Wagens and blame them as rust prone, also G Wagens have had their share of mechanical problems, still its the best and true 4WD out there and there is few other that come close to it with the exception of Toyota FJ or Nissan Patrol.
